Payment icons NON EXISTENT

[wonderboy]

Hi,

I need urgent help please.  I am trying to add payment icons on my website using the Porto 3.5.1 theme.  I want my payment icons to show up at the bottom under the copyright footer.  I have used and seen the help center section which shows replace the code in the footer 

{% for type in shop.enabled_payment_types %}

then replace it for the other.

The problem is I can't find that code anywhere in the foot or theme code page.  No where on any code page in the back end have I got any code that says payment.

I have tried looking on the website editor but shows nothing in the footer setting section that allows me to enable payment icons.

Would really appreciate somebody that can help or advise me on what do and how?

Thanks
Moe
